AI Technical Summary

Problems solved by technology

However, when the number of nodes increases and the number of requests increases sharply, the performance of the highly robust Byzantine fault-tolerant algorithm will drop rapidly, and the prevention of node attacks is also relatively weak, making it difficult to meet the requirements of data security and real-time on-chain

Embodiment Construction

[0043] Based on the specific embodiments and the accompanying drawings, the related technologies involved in the present invention will be described and explained in detail. Except for the content to be mentioned below, other techniques and methods related to implementation conditions of the present invention are common knowledge and common knowledge in this field and its related fields.

[0044] The present invention proposes a secure real-time chaining method of consortium chain data based on high robustness Byzantine fault tolerance. The method is used in consortium chain network, and all nodes in the network follow the malicious node supervision mechanism; the network allows dynamic joining of nodes. Add nodes to join, then enter the node dynamic increase process. After the increase, if the number of nodes exceeds the set threshold, the partition management and partition consensus mechanism will be activated; and the signature sig for d(m) of the node sending this message;...

Abstract

The present invention proposes a method for secure real-time chaining of consortium chain data based on high robustness Byzantine fault tolerance. And the fast batch processing mechanism can improve the ability of the alliance chain network to process a large amount of data on-chain requests in a short time, and can use the partition management and partition consensus mechanism in the scenario of a large number of nodes in the consensus network to achieve with low latency. The data is uploaded to the chain to achieve the effect of real-time chaining. At the same time, this method adds a malicious node supervision mechanism, which can prevent the Byzantine behavior of malicious nodes and improve the robustness of the alliance chain network.

Description

technical field [0001] The invention relates to a consortium chain Byzantine fault-tolerant algorithm, belongs to the technical field of block chains, and in particular relates to a consortium chain data security real-time chaining method based on high robustness Byzantine fault tolerance. Background technique [0002] With the widespread popularity of the Internet in various industries, the speed and security of data transmission, storage, and security have been greatly challenged: on the one hand, data is easily intercepted by hackers during transmission, or messages cannot be delivered to the target due to network fluctuations On the other hand, due to the surge in the number of users, the speed of the server processing data will be greatly tested, and the synchronization of data between various servers will also become one of the architectural considerations. [0003] The distributed consensus network of blockchain has the characteristics of decentralization, data tamper...
